UNITED STATES PATENT OFFICE MICHAEL A. S. LAVIGNE, OF WINSTED, CONNECTICUT, ASSIGNOR F SEVENTEEN PER CENT TO AMIN M. KHOURY,

OF BURLINGTON, VERMONT OIL BURNER Application filed April 11,

This invention relates to new and useful improvements in oil burners, its primary object being to provide an oil burner that will generate a combustible gas by vaporizing the crude oil fuel without any forced draught or other mechanical aid. This is accomplished by having an oil trough, in which the fuel is burned, in the base of the apparatus and a plurality of perforated partitions situated around the said oil trough and having a plurality of parallel passages extending around and between said partitions and outer casing, which form the the draft passages and the combustion chamber.

Another object of the invention is to provide an oil burner of the character described that is inexpensive to manufacture in consideration of the advantages offered, efficient and durable in service, positive in action and a general improvement in the art.

Another important feature of the invention is that owing to the manner in which the partitions are held in place, they may be easily renewed when they become burned by the 25 excessive heat. This also applies to the top bafiles which are likewise subject to the heat.

With these and other objects in view as will appear as thedescription proceeds, the invention consists in the novel construction and 30 arrangement of parts as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of this presentapplication and in which:

Fig. 1 is a perspective View showing com- 35 plete installation of my invention in a typical domestic furnace.

Fig. 2 is a side elevation of the oil burner. Fig. 3 is a plan view of the oil burner with top bafiles partially removed.

Fig. 4 is a cross-section along line A A of Fig. 3.

Fig. 5 is an enlarged view of ball and socket joint of the stand.

Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views it will be seen that the invention comprises a base in which is located a shallow oil trough 11 and a feed passage 12 into which is connected a feed pipe 13. Sup- 1928. Serial N'o. 269,206.

ported on this base in grooves or checks pro vided therefor are two perforated partitions, an inner one 14 and an outer one 15, the space between them forming the combustion chamber 16 and an outer casing 17. A number of baflles or covers are provided and are checked in a similar manner to the base to receive the perforated partitions 14 and 15 and the outer casing 17 The center bafile 18 is fitted to the inner partition 14 while the outer balfie 19 is fitted to the outer partition 15 and the outer casing 17, and forms a cover for the outer draft passage 20. The bafiie 21 forms a cover for the central draft passage 22. Suitable spaces 23 are provided in the base 10 to permit the air to enter these draft passages and 22. 24 is a flame bafile located immediately above the oil trough 11, its purpose being to assist in breaking up the flame. The outlet 25 is in the baffle or cover 21 at the upper end of the combustion chamber. A priming trough 26 is placed underneath the base 10 and is'connected to a pipe 27 extending outwards to a filler 28 having a lid 29. Extending over the entire apparatus is a canopy 30 supported on a pipe 31. The pipe being in turn Supported at the top by :1 lug 32 on the baffle 19 and near the bottom by a lug 33 on the base 10. The lower end of the said pipe 31 is connected to the pipe 27 and in this manner supports the priming trough 26. The stand 34 is connected to the base 10 by a ball and socket joint 35 having a tightening bolt 36 and a nut 37, as a means of permitting the oil burner to be perfectly levelled when setin the fire box of a furnace. A needle valve 38 and float 39 are used to supply a constant front and filler spout 44 of an oil gauge glass 45 on the side of same.

It will be seenfrom the foregoing paragraphs that in order-to light the burner a supply of gasoline is first poured into the priming trough 26 through the filler a match is then applied to the gasoline in the filler and the lid 29 closed down, which will cause the flame to come out around the primihg trough 26 and heat the oil in the oil trough 11. This combined with air which will be drawn in through the air inlets 23 and into the draft passages 20 and 22 then through the perforations in the partitions 14 and 15, will generate a combustible gas in the combustion chamber which will become ignited from the flames of the burning gasolne. trough is consumed the burner will be sufficiently heated to generate the gas from the inflowing fuel oil without any supplementary side. The object of the canopy 30 is to reflex the heat onto the burner. The unburned gas and a quantity of heated air is carried down the pipe 31 and released from the priming trough to re-enter the burner through the air inlets 23. The pre-heated air will more readily form the combustible gas than the cold. Thus it will be seen that the greater heat that is obtainable the greater will be the consumption of the air and therefore a greater economy in the fuel oil.

It is believed that the construction and advantages of the structure shown may be apparent from the foregoing paragraphs taken in connection with the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it is understood Vhen the gasoline in the priming MlCHAEL A. S. LAVIGNE.

that minor changes in the details of construct-ion combination and arrangement of cooperating elements may be resorted to With in the scope of what is claimed without departing from-the spirit of the invention.

\Vhat I claim is 1. An oil burner, comprising a base member, a fuel trough supported by said base member, spaced perforated partitions extending vertically from the walls of said trough, forming a combustion chamber above the trough, an outer wall disposed in spaced relation to the outer partition and supported by said base member, a cover for said partitions and wall having openings therethrough comlmlnicating with the combustion chamber,

a canopy disposed above said cover in spaced relation thereto, a priming trough disposed beneath the base member adjacent the fuel trough, a filler pipe connected with said priming trough, and a return pipe extending down from said canopy having connection with said filler pipe, said base member having air openings communicating with the space between the outer wall and outer partition.

2. An oil burner, comprising a base member, a fuel trough supported by said base member, spaced perforated partitions extending upwardly from the walls of the trough forming a combustion chamber, an outer Wall spaced from the outer partition supported by the base member and forming an air chamber,
